I was receiving masses of these calls sometimes up to three in the same day, despite giving different responses. Telling them to eff off, explaining that I had never been a BT customer and never would be, and so on.

Eventually I lost patience with them (if you have caller display on your phone and happen to see the display as the call starts you will see International Call flash up, quickly replaced by 02075676666 number or similar). The next time I saw that number I answered the phone with “Scottish Police, Inspector Jack Frost Denton CID, thank you for calling, we’ve been waiting for your call….” They rang off immediately and we’ve now had three weeks without receiving another call from them. It may be coincidence, but it does seem to have done the trick
